Congratulations on your purchase of the new patent pending HUM EXTRACTOR
™ + DECIMATOR
G
™ pedal. The HUM EXTDECIMATOR G™ pedal was designed to provide the ultimate
sonic performance possible for removing line frequency hum components from an instrument signal.
Guitar and Bass instruments are susceptible to noise intrusion from AC line frequency
electromagnetic fields. This kind of electromagnetic interference is typically picked up by the
instrument pickups, although these hum frequency components can also be injected into audio
signals by bad cables or other means of intrusion. The fundamental hum component is at the AC
line frequency with many multiple harmonically related components above the fundamental
frequency. The line frequency is selectable for 60 hertz or 50 hertz operation. Adjustments for HUM
EXTRACTOR and DECIMATOR threshold settings plus the dynamic filter tracking are automatically
stored and will be retained on power off. The HUM EXTRACTOR +DECIMATOR G can remove
these hum components from the audio signal with amazing transparency reducing the requirement
of the DECIMATOR single ended noise reduction to only have to work on gain noise and hiss. The
DECIMATOR is controlled from the direct instrument input allowing the noise reduction to work
perfectly when switching between high gain and clean settings. The DECIMATOR block
incorporates ISP Technologies full DECIMATOR as included in the professional ProRack G which
includes both a low level downward expander and a dynamic sliding low pass filter. This allows
removal of high frequency hiss and noise while playing at full volume. The combination of both the
HUM EXTRACTOR and DECIMATOR provides the most effective noise reduction system available
for eliminating virtually all noise from the input signal with incredible transparency.
